T. GUILLEAUME. FENCING WIRE.

Patented May 9, 1893.

UNITED STATES PATENT OFFICE.

THEODORE GUILLEAUME, OF COLOGNE, GERMANY.

FENCING-WIRE.

SPECIFICATION forming part of Letters Patent No. 496,974, dated May 9,1893.

Application filed August 18, 1892' Serial No. 443,423. (No model.)Patented in Belgium July 22, 1892,1l0. 100,639: in France July 23, 1892,No. 223,185, and in Canada September 14, 1892, No. 40,337.

To 00% whom it may concern.-

Be it known that LTHEoDoRE GUILLEAUME, a subject of the German Emperor,residing at Cologne, in the German Empire, have invented new and usefulImprovements in Fencingire, (for which I have obtained Letters Patent inFrance July 23, 1892, No;

223,185; in Belgium July 22, 1892, No. 100,639, and in Canada September14, 1892, No. 40,337,) of which the following is a specification.

This invention relates to twisted fencing wire, and consists in theemployment of. two wires each of which is triangular in cross section;when both wires are laid together base to base, a cross section ofdiamond shape being presented.

In the accompanyingdrawings, which serve to illustrate my invention,Figure l is a side elevation of a piece of the improved twisted fencingwire furnished with barbs; Fig. 2 being a section on the line 2, 2 inFig. 1.

A and A are the two triangular wires twisted together; 0 being thebarbs.

Fencing wire formed of two triangular wires in comparison with fencingwire formed of cylindrical wires of equal sectional area has a largersuperficial area and is therefore more readily seen. Owing moreover toits sharp edges, it has a deterrent eifect on human beings and animals.Twisted bipart diamond Wire of the kind above described may, as shown inthe drawings, be employed as the body wire in barb wire for fencingpurposes.

Under such circumstances, instead of laying one member of the main orbody wire outside the coils of the wire constituting the barb (in orderto prevent the latter turning and sliding on the other member of themain or body wire, about which it is coiled), the coils of each barb Oenvelop both parts A and A of the body wire; but, owing to the sectionalform of the latter, the barb is prevented turning and sliding thereon.The process of. manufacture is moreover both simplified and cheapened;inasmuch as the barb-wire coils are applied to the already-twisted mainwire, instead of the twisting process being carried out after the barbshave been applied.

I am aware that the employment of a single spirally-twisted wire oftriangular, square or other regular or irregular section, for use as themain or body wire of barb-Wire fencing, has been proposed by Glidden,l-Iaish and others; but, as compared with any such mode of manufacture,this invention presents distinct advantages, inasmuch as thehereinbefore-described improved barb-wire fencing can be manufactured ingreater lengths free from join t, is more elastic and therefore morereadily accommodates itself to the effects of heat and cold, and, in thecourse of manufacture, is more easily twisted than a diamondshaped wireof the same cross section, but solid insteadof in two parts.

What I claim as my invention, and desire to secure by Letters Patent,is-

- 1. The improved fencing Wire consisting of two triangular wires A andA laid base to base and twisted together, substantially as hereindescribed.

2. The improved fencing wire consisting of two triangular wires A and Alaid base to base and twisted together, and furnished with barbs C,substantially as herein described.

3. In fencing wire, the combination, with two triangular body wires Aand A laid base to base and twisted together, of a barb wire (J coiledabout both members of the twisted bipart body wire, substantially asherein set forth.
